[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine, and more particularly to a gaming machine in which a ball passage member that forms a passage for a gaming ball is grounded by being attached to a device body.
[0002]
[Prior art]
A gaming machine such as a pachinko machine is configured such that the inner frame can be opened and closed on the outer frame installed on the island facility that constitutes the outer shell of the equipment body, and on the front side of the inner frame, a game board, a glass frame, A hitting ball supply tray, a launching handle, and the like are disposed, and a back set (mechanism frame) provided with an upper tank and a lower tank for storing a prize ball, a prize ball payout device, and the like is attached to the back surface of the inner frame. In recent years, this back set is made of a conductive resin material, and connected to the ground terminal (grounding) of the island facility via a conductive wire or the like, and a ball such as a game board or a hitting ball supply tray that forms a path for a game ball By connecting the passage member to the back set using a conductive wire (ground wire), a configuration is adopted in which static electricity charged on the ball passage member due to contact / friction of the game ball is discharged to the back set side.
[0003]
On the other hand, recently, a so-called “left-handed” model has been developed in which a hitting ball launching device is arranged at the lower left of the game board and hits the hitting ball upward. In the case of this model, a ball hitting device provided in the inner frame of the conventional model and arranged at the lower right of the game board, or a shot launched near the lower right of the game board is directed to the upper left side of the game board. This eliminates the need for a guide rail or the like that leads to the side of the game board, and therefore has the advantage of making it easier to expand the game area by utilizing the empty space generated on the lower side of the game board.
[0004]
Along with this, the hitting ball supply tray (upper plate) and the surplus ball receiving tray (lower plate), which were previously divided into two parts, are configured as an integrated dish that combines these functions and placed lower than the conventional upper plate height. In addition, a ball storage member (storage tank) that stores game balls that cannot be stored in the ball tray part of the integrated dish is provided on the back side of the integrated dish, ensuring a storage amount equal to or greater than that of conventional ones. Many changes have been made such as making it possible (see, for example, Patent Document 1).
